IMPROVEMENT IN TlRE-UPSETTERS. u

Specification forming part of Letters Patent No. 173,060, dated February 1, 1876; application filed November 13,1875.

on pivots so as to adjust automatically to tires of any radius, and it also consists of a novel eontrlvance of the pivots forboth the stationary and movable jaws, contrived so that the resistance is taken directly by the supportingblocks instead of being expended on pivot bolts, whereby a more-substantial and desirable arrangement is obtained.

Figurel is'a longitudinal sectional elevation of my improved tire-upsetter, taken on line 00 m of Fig. 2; and Fig.2 is a plan view;

Similar letters of reference indicate corre- A represents the jaws, against whichthe tire is griped by the pivoted jaws B,and which are coin nionly made stationary, but which are, according to my improvement, fixed on posts U,'so that they can. be readily shifted to suit tires of any curves; and they are provided with an adjusting-screw, D, by which to, set them in any position desired after being shifted. Thus the jaws will work equally as well on tires of any size. These pivots, and also Witnesses the pivots of the jaws B, I construct by making a half-round rib, a, on the face or wall of the supporting-block E, and a corresponding groove in the jaws to fit on, and turn about,

the rib; and to keep the jaws in position, I

the lever contrivance for a hand-power cutting-machine.

' Having thus described my invention, I claim as neW,-and desire to secure by Letters Patent- I 1. The jaws A, mounted on pivots O, having an adjusting-screw, D, substantially as specified.

2. The combination, in a tire-upsetter, of the supporting-blocks E, having a rib, a,'and

the jaws A B, provided with a groove, substantially as and for the purpose set forth.-
